I n my N. PETERS, FHOTOJJTIIOGHAPNER. WASHIiIGTON D C UNITED STATES PATENT OFFIC LEWIS SCOTT, OF BRIGHTON, MICHIGAN.-

I IMPROVEMENT IN LATTICE-PIERS FOR TIMBER TRUSS-BRIDGES.

Specification forming part of Letters Batent No. I 79,964, dated July 18, 1876; application filed April 18, 1876.

To all whom it may concern:

Be it known that I, LEWIS SCOTT. of Brighton, Livingston county, Michigan, have invented new and useful Improvements in Bridges, of which the following is a specification:

The invention will first be described in connection with drawing, and then pointed out in the claim.

Figure 1 is an end elevation, and Fig. 2 is a top view.

Similar letters of reference indicate corresponding parts.

J J represent two sets of posts, so arranged in a truss-bridge that they will incline in opposite directions, and be located on opposite sides of the girts K. They are all sustained upon a common base, L, that is thus connected with the superposed beam M, so as to form a re-enforcement brace or support to each other. This has the efi'ect of dividing and evenly distributing the weight or strain along the whole length of the foundation or base.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In truss-bridges the two sets of posts J, inclined reversely and on opposite sides of the girts K, all the posts sustained upon a common base, L, connected with an upper beam, M, and supporting each other, substantially as shown and described.

LEWIS SCOTT.
